[0002] In the process of drilling underground, the treatment of gas spray holes in coal seams is an important issue related to the overall mine operation effect. In addition to spraying gas, the gas spray holes will also carry out coal slag and other fine dust particles. Therefore, it is necessary to carry out a certain degree of slag removal and cleaning of the gas from the spray holes. The applicant filed a patent application number of 2020224500607 in 2020 for "A device for removing slag from drilling anti-gas spray holes in mines" in order to improve the separation effect between groundwater, coal slag dust and underground gas and other gases; and in 2023 for the above patented equipment The separation box has been improved and designed to realize a device for timely removing the coal slag retained in the separation box. The application number is 2023222153475, and the patent name is "A rotating device for removing coal slag on a blowout prevention device"; but according to the actual feedback from operators on the coal mine, there is still a problem of a large amount of coal slag in the underground gas extracted through the negative pressure pipe; this is because the slag removal equipment used in the past cannot effectively remove the suspended coal slag in the air; based on this, it is necessary to design a new slag removal device for use in the gas-slag-water separation box.
